no-classic-classes: getSourceModuleName should only be called on a CallExpression, MemberExpression or Identifier

AssertionError [ERR_ASSERTION]: `getSourceModuleName` should only be called on a `CallExpression`, `MemberExpression` or `Identifier`

is triggered by:

import thing from 'place';

export default class Cls {
  init() {
    this.extend();
  }
}

(without the import statement, even though it's unused, the error will not happen).

• eslint@7.20.0
• eslint-plugin-ember@10.2.0
• ember-source@3.25.1
• ember-cli@3.25.0

Looks similar to #905, but it was fixed by #906 which was released in v8.10.1 and I'm seeing this in 10.2.0.

Perhaps also noteworthy that it repros with this.member.chain.extend() in place of this.extend(). My actual use case is the CKEditor schema API:

import Plugin from '@ckeditor/ckeditor5-core/src/plugin';

export default class TaggingEditing extends Plugin {
  init() {
    this.editor.model.schema.extend('$text', { allowAttributes: tagAttribute });
    // ...
  }
}
